My host has replaced Apache with LiteSpeed.

This is what their site says:

LiteSpeed Web Server is the leading high-performance, high-scalability web server. LiteSpeed Web Server has superior performance in terms of both raw speed and scalability. Our benchmarks demonstrate that it is more than 6 times faster than Apache. When serving static content, LiteSpeed surpasses well-respected content accelerators including thttpd, boa and TUX. When it comes to dynamic content, LiteSpeed is more than 50% faster in PHP content delivery than Apache with mod_php.
Is it true?
